CHARLES B. RUMSEY, OF BINGHAMTON, NEW YORK.

SUPPORTING-FRAME FOR ENGINES.

SPECIFICATION forming part of Letters Patent No. 688,342, dated, De emb10, 1901. Application filed March 31, 1900. Renewed October 19, 1901. Si l No. 79,283. (No model.)

To aZZ whmn it may concern;

Be it known that I, CHARLEs'B. RUMsEY, a citizen of the UnitedStates,resid in g at Binghamton, in the county of Broome and State ofNew York, have invented certain new and useful Improvements inSupporting-Frames for Engines; and I do hereby declare the following tobe a full, clear, and exact descrip tion of the invention,s.uch as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to framesor runninggear for supporting gas andother engines; and it consists, essentially, of forming the crankcase ofan engine and the front and rear bars, which connect the respectiveaxles together, preferably in one piece. This peculiar constructionenables me to position the working points of the engine low down, thusavoiding top-heaviness.

The invention further consists in providing or forming the crank-casewith hollow pro- .jecting side arms to form bearings for thecrank-shaft. Theinvention still further consists in providing thecrank-case with a suitable seat for supporting the engine-cylinder.

The principal object of the invention is to provide a support of thecharacter mentioned which will embrace the necessary elements ofcompactness, simplicity, and cheapness and at the same time be efiectualin supporting the engine and its working parts and durable in use.

Other objects will become apparent upon further description of theinvention.

Iu'the accompanying drawings, Figure 1 is a side elevation of myimproved engine-supporting frame, partly in section, to show theinterior of the crank-case with the cylinder seated in position; Fig. 2,a transverse vertical section through the crank-case; Fig. 3, ahorizontal section through the same, showing the location of thewater-tank; Fig. 4, a perspective view of the preferred form of myimproved frame or running-gear, and Figs. 5 and 6 a modified form ofrear bar for attachment torear axle and for supporting water-tank.

Referring to the several views, the numeral 1 indicates the axles, and 2the wheels, of an ordinary portable engine.

The numeral 3 indicates my improved frame or running-gear for supportingthe engine. The frame consists of a crank-case 4:, a single frontextension or bar 5, and preferably two rear extensions or bars 6, asshown in Fig. 3. The front extension is preferably curved, as shown inFig. 1, and is formed at its extreme forward end with a socket 7, whichis adapted'to receive a ball 8 of a clip-iron 9, attached tothe frontaxle. The ball is confinedin the socket by a perforated plate 10, boltedto the extension, the whole forming a ballandsocket connection betweenthe axle and supporting-frame to allow for the free cutting on the frontwheels. It will be understood that any other form of coupling betweenthe axle and support may be employed which will permit the wheels to outunder on either side. The front extension is formed of a vertical web11, having outwardly-extending bottom flanges 12, which unite with andhave their sides flush with the crank-case. sions curve outwardly andrearwardly from a central vertical web 13, and the outer side of eachextension is formed with an outwardly extending flange 14,which alsounites with the crank-case and has its side edge flush therewith. Eachside of the crank-case is formed with a hollow arm 15, which forms abearing for the crank-shaft 16. The upper part of the crank-case isformed with a seat 17. to which the cylinder 18 is bolted. The seat 17is formed with an opening 19, through which the pitman 20 and piston20' operate.

While I have preferred to form the supporting-frame with two rearextensions, so as to partially embrace the water-tank 21 of the engine,itmay be formed with a single broad extension, as shown in Figs. 5 and6, in which case a vertical web 22 extends from the crankcase and hasformed on its upper edge a broad platform 23, which extends downwardlyand has formed therein a bore 24 for the reception of the axle. Theplatform serves as a seat for the water-tank, which may be attached toit by any suitable means.

Other changes may be made without departing from the spirit of myinvention or sacrificing the principle thereof, and the front extensionsmay be provided with a seat-support 25, to which a seat for the drivermay be attached.

Having thus fully described my invention,

what I claim, and desire to secure by Letters Patent, is-

l. A supporting-frame for portable engines consisting of front and rearextensions for attachment to the respective axles,- a crankcase integralwith said extension and formed with bearings for the crank-shaft andwith a perforated seat-support for the engine-cylinder, saidseat-support being integral with the crank-case and extensions, as setforth.

2. A supporting-frame for gas and other engines, consisting of one frontand two rear extensions adapted to be attached to the respective axlesof the machine, a crank-case integral with said extensions and formedwith crank-shaft bearings, and a perforated cylinder-snpporting seat,said supporting-seat being integral with the crank-case and extensions,as set forth.

3. A supporting-frame for gas and other engines, consisting of acrank-case formed with shaft-bearings, and with a perforatedcylinder-supporting seat, a front extension integral with saidcrank-case and formed with a vertical Web also integral with saidcrankcase, and a bifurcated rear extension integral with said crank-easeand formed with a vertieal Web, also integral with the crank-case, asset forth.

.4. As an article of manufacture, a supporting-frame for engines, castor molded in one piece, the same consisting of a crank-case, formed withshaft-bearings and perforated cylinder-supporting seat, and with frontand rear extensions for attachment to the respective axles.

In testimony whereof I afiix my signature in the presence of twowitnesses.
